after you do the HENC and it goes blue. then you do the Devhook .4x after that comes to the black screen with the options. Got to Firmware and change it from 2.71(flash) to the one at the very bottom which is 2.71. Then click the UMD select and select the ISO that you have. And then click ont the "start" and you will reboot again. Remember you need to make sure you have the UMD popped out from the very beginning of this entire process even before you do the HENC othervwise you will have to start over.
